Bitcoin mining remains one of the most intriguing aspects of the cryptocurrency ecosystem. While the process may seem complex, understanding mining profitability boils down to a few key metrics: hashrate, power consumption, electricity cost, and network difficulty. In this guide, we’ll break down exactly how much a single terahash (1T) of mining power can earn per day, using real-world parameters and a widely used mining rig — the Bitmain Ant S17+ — as our reference.
Whether you're a beginner exploring mining economics or an experienced operator optimizing returns, this article delivers actionable insights with clear calculations, SEO-optimized keywords, and practical examples.
Understanding Bitcoin Mining Profitability
At its core, Bitcoin mining rewards are determined by how much computational power (hashrate) a miner contributes relative to the total network hashrate. The higher your share, the greater your chance of earning block rewards.
To calculate daily earnings from 1 terahash (TH/s), we need to analyze:
- Individual miner performance
- Electricity costs
- Current network conditions
- Daily Bitcoin output
Let’s walk through each step.
Key Parameters for Mining Calculation
We’ll use the Bitmain Ant S17+ as our benchmark device due to its widespread adoption and reliable performance data.
Device Specifications:
- Hashrate: 73 TH/s
- Power Consumption: ~3,000 watts (3 kW)
- Efficiency: ~41.7 J/TH (joules per terahash)
External Factors:
- Electricity Cost: ¥0.33 per kWh (approximately $0.046 USD)
- Network Hashrate: ~93 exahashes per second (EH/s) — current average
- Block Reward: 6.25 BTC per block (pre-halving); adjusted to 3.125 BTC post-halving in 2024
- Blocks per Day: ~144 (one block every 10 minutes)

Step-by-Step: How Much Does 1T Earn Per Day?
Step 1: Calculate Total Daily Network Rewards
Bitcoin generates approximately 144 blocks per day. With a block reward of 3.125 BTC, the total daily BTC issuance is:
144 blocks × 3.125 BTC = 450 BTC/day
This means miners collectively earn 450 BTC every 24 hours.
Step 2: Determine Your Share of the Network
The global hashrate is currently around 93 EH/s, which equals 93,000,000 TH/s.
If you control 1 TH/s, your share of the network is:
1 ÷ 93,000,000 ≈ 0.000001075%
So, your daily BTC earnings would be:
450 BTC × 0.000001075 ≈ 0.00048375 BTC per day per TH
That’s about 48,375 satoshis daily for every 1 terahash of power.
Step 3: Convert to Fiat Value
As of mid-2025, assuming a Bitcoin price of $65,000, the value of 0.00048375 BTC is:
0.00048375 × $65,000 ≈ **$31.44 per day per TH**
This is gross revenue — before electricity and operational costs.
Step 4: Deduct Electricity Costs
Now let’s calculate energy expenses for running 1 TH/s.
The Ant S17+ delivers 73 TH/s using 3,000 watts. So, power usage per TH/s is:
3,000 W ÷ 73 ≈ 41.1 W per TH/s
Over 24 hours, that’s:
41.1 W × 24 h = 986.4 Wh = 0.9864 kWh/day per TH
At ¥0.33/kWh (~$0.046), the daily cost is:
0.9864 × $0.046 ≈ **$0.0454 per day per TH**
Step 5: Net Profit Per Terahash
Subtracting electricity cost from gross income:
$31.44 (revenue) – $0.045 (electricity) ≈ $31.39 net profit per day per TH
💡 This shows that at current network conditions and BTC prices, 1T of efficient mining power generates over $31 daily, with minimal operating costs.
Factors That Influence Mining Returns
While the above calculation assumes stable conditions, several variables affect actual profitability:
- Bitcoin Price Volatility: A drop to $40,000 reduces daily earnings to ~$19.25 per TH.
- Network Hashrate Growth: Increased competition lowers individual rewards.
- Halving Events: Reduced block rewards directly cut miner income in half.
- Electricity Cost Variance: Miners paying $0.10/kWh or more may see negative margins.
- Hardware Efficiency: Older models like the Ant S9 are no longer profitable under most conditions.

Frequently Asked Questions (FAQ)
Q: Is Bitcoin mining still profitable in 2025?
A: Yes — but only with low electricity costs (<$0.06/kWh), efficient hardware (e.g., Ant S19 series or newer), and access to reliable infrastructure. Large-scale operations dominate, though small miners can profit via pooled mining.
Q: How much does it cost to run 1 TH/s per month?
A: At $0.046/kWh and continuous operation, electricity for 1 TH/s costs about $1.36/month. Hardware depreciation and cooling add minor overhead.
Q: Can I mine Bitcoin profitably at home?
A: Rarely. Residential electricity rates are typically too high ($0.12+/kWh), and noise/heat make home setups impractical. Industrial hosting or cloud mining may be better options.
Q: What happens when network hashrate increases?
A: As more miners join, the difficulty adjusts upward, reducing individual payouts unless you scale your operation.
Q: How long does it take to recoup a miner’s cost?
A: With current pricing and efficiency, modern ASICs like the Ant S19 can break even in 8–14 months under optimal conditions.
Q: Does mining pool membership affect my earnings?
A: Pools increase consistency by combining hashrate and distributing rewards proportionally. Fees are usually low (1–2%), making them essential for small operators.

Final Thoughts: Mining in the Modern Era
Bitcoin mining has evolved from a hobbyist activity into a capital-intensive industry dominated by large farms in regions with cheap energy — particularly hydroelectric or stranded power sources.
However, individuals can still participate through hosted mining services or by investing in efficient rigs where electricity is affordable.
The key takeaway? Profitability hinges not on raw hashrate alone, but on energy efficiency and cost control. Even with falling block rewards post-halving, well-positioned miners continue to generate strong returns — especially when leveraging real-time monitoring tools and market insights.
